How to choose aluminum for CNC machining
Start with the part’s operating environment and the features that control fit. Load, corrosion exposure, weight and the required surface finish all influence the alloy and temper to review.
A general-purpose housing, a structural bracket and a fluid-system manifold can call for different material decisions. Compare the grade options against your drawing, and identify which requirements are fixed and which can be discussed.
Before requesting a quotation, share the current drawing revision, preferred grade and temper, quantity and finishing requirements. Material availability, the machining approach and the inspection scope should be confirmed for the specific part.
